Help Identifying Correct Governor Adapter for 0320

Hello
Wondering if anyone can help me identify the correct governor adapter and other parts for my 0320 and best place to purchase these parts.

0320 experimental built by Lycon 20 years ago. Not sure of the model number, using the Lycoming Parts Catalog PC-203-2 0320 B and D Series

I?m trying to determine the difference between the 75153 adapter assembly for Woodward governor installations and the 75545 for ?AN? governor installations. Think I need to use the 75545 but not 100% sure.

Planning to use:
PCU 5000X governor
75167 SS oil line
MS20822-6 fitting for the font of the crank case
74070 45 deg. fitting for the adapter

Appreciate any help you can provide.
Thanks
Pat

Aircraft Specialty Services (www.aircraftspecialties.aero) and Aircraft Spruce are good sources for these supplies. As for which governor adapter, I'd search for the Lycoming Parts Catalog for specific model engine. I've always found that a reliable way to verify the part numbers.
